This is a single-arm, open label, before-and-after exploratory trial to evaluate the effect of 4 weeks of BCP administration on serum liver enzymes and the metabolic syndrome in patients with NASH. Candidates will be identified from among the patients treated in the department of medicine and liver unit of the Hadassah Hebrew University Medical Center and will be asked to sign an approved informed consent from before any study activities are initiated. Participants will be followed on study with weekly visits as well as for an additional 4 weeks after concluding treatment to assess safety.
